"So, are you really going to look for clues under that bridge?" Yan Sixian sat behind Wu Duan's desk and asked while browsing the information on the computer.

Wu Duan, who had just come back from the interrogation room, saw that he didn't treat himself as an outsider so much, so he said angrily: "Go to the logistics to move a set of tables and chairs, don't use mine!" ”

"How about a bet? If I solve this case, you go and move the table for me, if you solve it...... Well...... Forget it, it can't be. ”

Wu Duan: Is there no longer any age, gender, or race for bears?

Wu Duan turned around and walked out the door.

Yan Sixian: "Why are you going?" ”

"Under the bridge, solve the case."

"Hey, don't be angry," Yan Sixian stopped him again, "You don't want to hear the results of my investigation?" Maybe it will help you. ”

In line with the attitude of "caring about the progress of new colleagues", Wu Duan stopped.

"Say it."

"I went to the paper mill where Xi Jingguo works, the paper mill is in the suburbs, the working conditions are quite bad, and when I went, it was lunchtime, and the food in the factory was boiled cabbage and steamed buns, and there was no oil at all – but that wasn't the point.

Xi Jingguo took leave and went home, saying that it was because he drank with Xi Lele on the night of the crime, drank his stomach badly, and went home to recuperate, I went to Xijia Village to look for him, and he was not at home - oh, that's not the point. ”

Wu Duan sat down on his desk and looked at Yan Sixian condescendingly, "Do you have a point?" ”

"There are some and there are some and there are here, and the point is: near the paper mill, almost a wall away, is a chicken farm."

Wu Duan opened his mouth, not knowing how to answer.

Yan Sixian was amused by his inexplicable expression, and continued: "Also, there are three dogs in the chicken farm, who are responsible for guarding the yard. ”

Wu Duan: "......"

"Hey, don't go, I'm not kidding, what I just said is really important information, it's just pieces of the puzzle, it hasn't been spelled out yet, it's normal to not understand, give me some patience, listen, I promise you don't want to go to that bridge hole."

Wu Duan sat down on the sofa in the office, "Listen up." ”

"I think that when you ask a suspect, you have to listen not only to what he said, but also to what he didn't say. For example, Xi Lele, he kept silent about stealing sheep back then. ”

"After all, it's not a glorious past, and it's understandable that I don't want to talk about it." Wu Duandao.

Of course, he doesn't want to tell others, it's understandable, but we are different, we are the police in charge of Xi Huanhuan's case, and he knows everything about us, whether it is as a victim's family, for the purpose of assisting the police to solve the case as soon as possible, or as a suspect, for the purpose of clearing his own suspicion.

However, when we mentioned the sheep theft case twice, he did it both times, and I didn't want to go into details, so I was even more interested in the sheep theft case.

It's a pity that the two sides negotiated a compensation settlement in this case, and the office process of the village police station was not standardized, so I had to go to Xijiazhuang to inquire about the family of the sheep who had been stolen back then.

I inquired about an interesting detail: back then, the family also had a dog.

It's not uncommon to have a dog, it's not unusual, it's rural.

However, when Xi Lele stole the sheep, he was afraid of the dog barking, so he poisoned the dog to death first—anyway, the owner saw the dog dead at the gate of the yard early the next morning, went to the sheepfold to take a look, and found that five sheep were lost.

The owner of this family is a heart, afraid that the dog will be poisoned, and if the villagers who are living in poverty pick up the dog corpse and go back to eat, it is easy to have an accident.

So the owner quietly buried the dead dog in a wooded area at the head of his house, and the owner led me to the place, where I dug up a few bones and some dog hair—there were some twists and turns in between, so I won't go into details. ”

Yan Sixian raised his hand, and Wu Duan saw a band-aid on the palm of his left hand, probably this young master had never done farm work, and the first time he touched a hoe and shovel, he injured himself.

Thinking of his clumsy digging of the soil, Wu Duan couldn't help but feel funny.

"I brought back what I dug up and asked Mink Fang to do a toxicology test, and the test result was: the dog died of poisoning by poisonous rats."

Wu Duan was a little stunned.

Yan Sixian continued: "Now, I can tell you a conclusion and a corollary.

Conclusion: The murderer is certainly not the one you captured.

I heard today that he smashed a woman with a brick in front of the supermarket, and in my opinion, this kind of superficial crime is not even within the scope of our 'criminal investigation'.

Do you think it is possible for such a person to poison the mother and daughter with meticulous methods the night before? Unless he has a split personality. ”

Wu Duan nodded, "Okay, I have to admit it, it makes sense, but what is ...... 'one inference'?" ”

Seeing that Wu Duan took the initiative to ask, Yan Sixian smiled with satisfaction, "Inference: The death of Xi Huanhuan's mother and daughter was an accident, and no one deliberately wanted to kill them." ”

"How?"

Of course Xi Jingguo knew that Xi Lele had stolen sheep, and even knew that even if the East Window incident happened, he lost money.

Next to it is a chicken farm, you say, Xi Jingguo, who has a very poor diet, has never had the intention of stealing a few chickens to fight for tooth sacrifice?

Once he has this in mind, who should he talk to? Of course, it's an experienced Xi Lele.

Xi Lele is a bold and righteous person, of course, he is talking about it, including taking poisonous rats and poisoning dogs - because there are also dogs in the chicken farm, or three - and even, Xi Lele, who can buy poisonous rats, also took the initiative to take over the work of making poisonous meat for dogs......"

Wu Duan interrupted: "I understand what you mean, you want to say that Xi Lele got a piece of meat with poisonous rats, originally intended to poison the dog in the chicken farm, but somehow it was eaten by Xi Huanhuan's mother and daughter."

But...... Stealing sheep was a few years ago, and Xi Lele has been honestly farming recently, and it looks like he has really washed his hands. ”

"Wash your hands in a golden basin? It depends on whether it is important to change the evil and return to the right, or whether it is important for the brothers to fight for righteousness. Besides, stealing chickens is a pleasure in itself. ”

"Innocuous hand-taking can make people happy, not the pleasure of taking advantage, but the pleasure of doing something new - you mean that?" Wu Duandao.

"Yes."

There was a moment of silence. Seeing that Wu Duan didn't say anything, Yan Sixian said, "How is it?" Have you surrendered to my wisdom? ”

Wu Duan shrugged, "The story is well told, how are you going to find evidence?" ”

Yan Sixian picked out one from a pile of photos of the scene on the table, and the photo was taken of the vegetable basket in the kitchen of the deceased's house.

The basket contained a cabbage, a few potatoes, two relatively clean carrots, and a bag of carrots stained with a lot of dirt.

"I've already figured it out, so I'll start with the carrot."
